TECHNOLOGICAL FIELD!

This invention relates to herbicides, and more particularly to N-phenyltetrahydrophthalamic acid derivatives which are novel compounds, to methods of producing the same, and to herbicides containing the same as the effective components, and to imidoylchloride derivatives as the intermediate products, and to methods of producing the same. N-phenyltetrahydrophthalamic acid derivatives of the present invention exhibit excellent herbicidal activity. The derivatives are useful as herbicides which can be widely applied to upland, paddy field, orchard, pasture, turf, forest, non-crop land, etc. The derivatives are not harmful to crops.

BACKGROUND TECHNOLOGY!

Hitherto, herbicidal activity of tetrahydrophthalamic acid derivatives is well known. For example, N-(4'-chlorophenyl)-3,4,5,6-tetrahydrophthalamic acid methyl ester is known, as is disclosed in JP-A-48-44425.

However, the conventional tetrahydrophthalamic acid derivatives are not necessarily sufficient in herbicidal activity or are substantially limited in herbicidal spectrum against weeds. Furthermore, these derivatives are insufficient in selectivity between crops and weeds, thereby inducing problems of safety for crops.

It is an object of the present invention to solve the aforementioned problems, and to provide novel compounds which are excellent in herbicidal activity but not harmful to crops, methods of producing the same and herbicides containing the same as the effective components, and the intermediate products and method of producing the same.

DISCLOSURE OF THE INVENTION!

An N-phenyltetrahydrophthalamic acid derivative I! which is a compound of the present invention can be produced, for example, as shown by the following formula, by reacting an imidoylchloride derivative represented by the general formula III! with a carboxylic acid represented by the general formula V!, ##STR8## wherein X and Y each individually represent hydrogen atoms or halogen atoms, R¹ represents a lower alkoxycarbonylalkylthio group, R² represents a lower alkyl group, a halogenated lower alkyl group or a substituted or unsubstituted phenyl group, and R³ represents a lower alkoxy group, a lower alkenyloxy group, a lower alkynyloxy group, or a lower alkoxyalkoxy group.

The reaction can proceed preferably without using any solvent or in a suitable solvent such as benzene, toluene, xylene, methylene chloride, chloroform, ethyl acetate, dioxane, tetrahydrofuran, diethyl ether, N,N-dimethylformamide or dimethylsulfoxide, by adding a suitable deacidifying agent such as an organic base such as triethylamine or pyridine, or an inorganic base such as potassium hydroxide or sodium hydroxide.

The present reaction is an equimolar reaction. Therefore, the molar ratio of an imidoylchloride derivative III! to a carboxylic acid V! is preferably about 1, and it is usually appropriately from 0.8 to 1.2. In case that it is less than 0.8, the imidoylchloride derivative III! which has been added in an excessive amount remains unreacted in a large amount. In case that it is greater than 1.2 by mol, the carboxylic acid V! which has been added in an excessive amount remains unreacted in a large amount. Therefore, it becomes impossible to effectively conduct the reaction, thereby causing an economical disadvantage. Furthermore, a burden in a purification process unpreferably increases, because it is necessary to remove or recover the unreacted imidoylchloride derivative III! or unreacted carboxylic acid V!. It is more preferably from 0.9 to 1.1 by mol.

In the present reaction, the addition of deacidifier in an amount of at least 1 by mol relative to the imidoylchloride derivative III! suffices. It is usually appropriately from 1 to 3 by mol. Less than 1 by mol is not preferable, because the reaction does not proceed sufficiently, causing a lowering of the yield. Even if an amount greater than 3 by mol is added, the reaction does not change so much, causing only an economical disadvantage. Furthermore, a burden in a purification process unpreferably increases, because it is necessary to remove an excessive deacidifier. It is more preferably from 1 to 2 by mol.

The reaction temperature is not particularly limited, and it is usually appropriately from -20° C. to 200° C. A temperature lower than -20° C. is not preferable, because it is impossible to obtain a sufficient reaction rate. With this, the reaction time becomes very long, and thus it becomes impossible to efficiently conduct the reaction. A temperature higher than 200° C. is not preferable, because the decomposition becomes violent. This causes a lowering of the yield. Furthermore, a burden in a purification process unpreferably increases, because it is necessary to remove the degradation product(s). It is more preferably from 20° C. to 70° C.

It is also possible to produce an N-phenyltetrahydrophthalamic derivative I! which is a compound of the present invention by reacting an imidoylchloride derivative represented by the general formula III! with an alkali metal salt of a carboxylic acid, represented by the general formula VI!, as shown in the following formula. ##STR9## wherein X and Y each individually represent hydrogen atoms or halogen atoms, R¹ represents a lower alkoxycarbonylalkylthio group, R² represents a lower alkyl group, a halogenated lower alkyl group or a substituted or unsubstituted phenyl group, R³ represents a lower alkoxy group, a lower alkenyloxy group, a lower alkynyloxy group, or a lower alkoxyalkoxy group, and M represents an alkali metal.

The reaction can preferably be conducted without using any solvent, or in a suitable solvent such as benzene, toluene, xylene, methylene chloride, chloroform, ethyl acetate, dioxane, tetrahydrofuran, diethyl ether, N,N-dimethylformamide, dimethylsulfoxide or water, if necessary, by adding a phase transfer catalyst.

The present reaction is an equimolar reaction. Therefore, the molar ratio of an alkali metal salt of carboxylic acid VI! to an imidoylchloride derivative III! is preferably about 1, and it is usually appropriately from 0.8 to 1.2. In case that it is less than 0.8, the imidoylchloride derivative III! which has been added in an excessive amount remains unreacted in a large amount. In case that it is greater than 1.2, the alkali metal salt of carboxylic acid VI! which has been added in an excessive amount remains unreacted in a large amount. Therefore, it becomes impossible to effectively conduct the reaction, thereby causing an economical disadvantage. Furthermore, a burden in a purification process unpreferably increases, because it is necessary to remove or recover the unreacted imidoylchloride derivative III! or unreacted alkali metal salt of carboxylic acid VI!. It is more preferably from 0.9 to 1.1 by mol.

As examples of a phase transfer catalyst used in the present reaction, it is possible to cite, for example, crown ethers such as 18-crown-6-ether, polyethers such as polyethylene glycol, quaternary phosphonium salts such as tetraphenylphosphonium chloride, and quaternary ammonium salts such as tetrabutylammonium bromide and tetrabutylammonium hydrogensulfate.

The amount of the phase transfer catalyst to be used is not particularly limited and may arbitrarily be adjusted depending on the desired reaction rate. It is usually appropriately from 0.01 mol % to 20 mol % relative to the imidoylchloride derivative III!. Less than 0.01 mol % is not preferable, because it is impossible to obtain a sufficient reaction rate. With this, the reaction time becomes very long, and thus it becomes impossible to efficiently conduct the reaction. Even if an amount greater than 20 mol % is added, the reaction does not change so much, causing only an economical disadvantage. Thus, this is not preferable. It is more preferably from 0.1 mol % to 10 mol %.

The reaction temperature is not particularly limited, and it is usually appropriately from 0° C. to 200° C. A temperature lower than 0° C. is not preferable, because it is impossible to obtain a sufficient reaction rate. With this, the reaction time becomes very long, and thus it becomes impossible to efficiently conduct the reaction. A temperature higher than 200° C. is not preferable, because the decomposition becomes violent. This causes a lowering of yield. Furthermore, a burden in a purification process unpreferably increases, because it is necessary to remove the degradation product. It is preferably from 0° C. to 100° C. for more efficiently conducting the reaction.

It is possible to produce an N-phenyltetrahydrophthalamic derivative II! which is a compound of the present invention, for example, by reacting an imidoylchloride derivative represented by the general formula IV! with a carboxylic acid represented by the general formula VII!, as shown in the following formula. ##STR10## wherein X' and Y' each individually represent hydrogen atoms or halogen atoms, R⁴ represents a hydrogen atom, a lower alkoxy group, a lower alkenyloxy group, a lower alkynyloxy group, cycloalkyloxy group, a lower alkoxycarbonyl group, a lower alkoxycarbonylalkoxy group or a lower alkoxycarbonylalkylthio group, R⁵ represents: ##STR11## wherein R⁷ represents a hydrogen atom, a halogen atom, a lower alkyl group or a lower alkoxycarbonyl group, and R⁸ represents a hydrogen atom, a halogen atom or a lower alkyl group and R⁶ represents a lower alkoxy group, a lower alkenyloxy group, a lower alkynyloxy group, a cycloalkyloxy group or a lower alkoxyalkoxy group.

The reaction can preferably be conducted without using any solvent, or in a suitable solvent such as benzene, toluene, xylene, methylene chloride, chloroform, ethyl acetate, dioxane, tetrahydrofuran, diethyl ether, N,N-dimethylformamide or dimethylsulfoxide, by adding a suitable deacidifier, for example, an organic base such as triethylamine or pyridine, or an inorganic base such as potassium hydroxide or sodium hydroxide.

The present reaction is an equimolar reaction. Therefore, the molar ratio of a carboxylic acid VII! to an imidoylchloride derivative IV! is preferably about 1, and it is usually appropriately from 0.8 to 1.2. In case that it is less than 0.8 by mol, the imidoylchloride derivative IV! which has been added in an excessive amount remains unreacted in a large amount. In case that it is greater than 1.2 by mol, the carboxylic acid VII! which has been added in an excessive amount remains unreacted in a large amount. Therefore, it becomes impossible to effectively conduct the reaction, thereby to cause an economical disadvantage. Furthermore, a burden in a purification process unpreferably increases, because it is necessary to remove or recover the unreacted imidoylchloride derivative IV! or unreacted carboxylic acid VII!. It is more preferably from 0.9 to 1.1 by mol.

In the present reaction, the addition of deacidifier in an amount of at least 1 by mol relative to the imidoylchloride derivative IV! suffices. It is usually appropriately from 1 to 3 by mol. Less than 1 by mol is not preferable, because the reaction does not proceed sufficiently, causing a lowering of the yield. Even if an amount greater than 3 by mol is added, the reaction does not change so much, causing only an economical disadvantage. Furthermore, a burden in a purification process unpreferably increases, because it is necessary to remove an excessive deacidifier. It is more preferably from 1 to 2 by mol.

The reaction temperature is not particularly limited, and it is usually appropriately from -20° C. to 200° C. A temperature lower than -20° C. is not preferable, because it is impossible to obtain a sufficient reaction rate. With this, the reaction time becomes very long, and thus it becomes impossible to efficiently conduct the reaction. A temperature higher than 200° C. is not preferable, because the decomposition becomes violent. This causes a lowering of the yield. Furthermore, a burden in a purification process unpreferably increases, because it is necessary to remove the degradation product. It is more preferably from 20° C. to 70° C.

It is also possible to produce an N-phenyltetrahydrophthalamic derivative II! which is a compound of the present invention by reacting an imidoylchloride derivative represented by the general formula IV! with an alkali metal salt of a carboxylic acid, represented by the general formula VIII!, as shown in the following formula. ##STR12## wherein X' and Y' each individually represent hydrogen atoms or halogen atoms, R⁴ represents a hydrogen atom, a lower alkoxy group, a lower alkenyloxy group, a lower alkynyloxy group, cycloalkyloxy group, a lower alkoxycarbonyl group, a lower alkoxycarbonylalkoxy group or a lower alkoxycarbonylalkylthio group, R⁵ represents: ##STR13## wherein R⁷ represents a hydrogen atom, a halogen atom, a lower alkyl group or a lower alkoxycarbonyl group, and R⁸ represents a hydrogen atom, a halogen atom or a lower alkyl group, and R⁶ represents a lower alkoxy group, a lower alkenyloxy group, a lower alkynyloxy group, a cycloalkyloxy group or a lower alkoxyalkoxy group, and M represents an alkali metal.

The reaction can preferably be conducted without using any solvent, or in a suitable solvent such as benzene, toluene, xylene, methylene chloride, chloroform, ethyl acetate, dioxane, tetrahydrofuran, diethyl ether, N,N-dimethylformamide, dimethylsulfoxide or water, if necessary, by adding a phase transfer catalyst.

The present reaction is an equimolar reaction. Therefore, the molar ratio of an alkali metal salt of a carboxylic acid VIII! to an imidoylchloride derivative IV! is preferably about 1, and it is usually appropriately from 0.8 to 1.2. In case that it is less than 0.8 by mol, the imidoylchloride derivative IV! which has been added in an excessive amount remains unreacted in a large amount. In case that it is greater than 1.2 by mol, the alkali metal salt of carboxylic acid VIII! which has been added in an excessive amount remains unreacted in a large amount. Therefore, it becomes impossible to effectively conduct the reaction, thereby causing an economical disadvantage. Furthermore, a burden in a purification process unpreferably increases, because it is necessary to remove or recover the unreacted imidoylchloride derivative IV! or unreacted alkali metal salt of carboxylic acid VIII!. It is more preferably from 0.9 to 1.1 by mol.

Even if an amount greater than 20 mol % is added, the reaction does not change so much, causing only an economical disadvantage. Thus, this is not preferable. It is more preferably from 0.1 mol % to 10 mol %.

The reaction temperature is not particularly limited, and it is usually appropriately from 0° C. to 200° C.

With this, the reaction time becomes very long, and thus it becomes impossible to efficiently conduct the reaction. A temperature higher than 200° C. is not preferable, because the decomposition becomes violent. This causes a lowering of yield. Furthermore, a burden in a purification process unpreferably increases, because it is necessary to remove the degradation product. It is preferably from 0° C. to 100° C. for more efficiently conducting the reaction.

Furthermore, an imidoylchloride derivative I! which is necessary as a starting material to obtain an N-phenyltetrahydrophthalamic acid derivative of the present invention can be produced, for example, using an anilide derivative represented by the general formula IX! as a starting raw material, ##STR14## wherein X and Y each individually represent hydrogen atoms or halogen atoms, R¹ represents a lower alkoxycarbonylalkylthio group, and R² represents a lower alkyl group, a halogenated lower alkyl group or a substituted or unsubstituted phenyl group.

The amount of dehydrochlorinating agent to be used is appropriately from 1 equivalent to 10 equivalents relative to the anilide derivative IX!. If it is less than 1 equivalent, the reaction does not proceed sufficiently, causing a lowering of the yield. Thus, this is not preferable. Even if an amount greater than 10 equivalents is added, the reaction does not change so much, thereby causing only an economical disadvantage. Furthermore, a burden in a purification process increases, because it is necessary to remove an excessive amount of the dehydrochlorinating agent. It is more preferably from 1 equivalent to 2 equivalents.

Furthermore, as preferable examples of the solvent used in the reaction, there can be cited halogenated hydrocarbons such as dichloroethane, carbon tetrachloride, chloroform and methylene chloride, aromatic hydrocarbons such as benzene, toluene, xylene and chlorobenzene, polar solvents such as acetonitrile and dimethyl sulfoxide.

The reaction temperature is not particularly limited, and is usually appropriately from 0° C. to 100° C. A temperature lower than 0° C. is not preferable, because it is impossible to obtain a sufficient reaction rate. With this, the reaction time becomes very long, and thus it becomes impossible to efficiently conduct the reaction. A temperature higher than 100° C. is not preferable, because the decomposition becomes violent. This causes a lowering of the yield. Furthermore, a burden in a purification process unpreferably increases, because it is necessary to remove the degradation product. It is more preferably from room temperature to 80° C.

Furthermore, an imidoylchloride derivative IV! which is necessary as a starting material to obtain an N-phenyltetrahydrophthalamic acid derivative IV! of the present invention can be produced, for example, using an anilide derivative represented by the general formula X! as a starting raw material, ##STR16## wherein X' and Y' each individually represent hydrogen atoms or halogen atoms, R⁴ represents a hydrogen atom, a lower alkoxy group, a lower alkenyloxy group, a lower alkynyloxy group, cycloalkyloxy group, a lower alkoxycarbonyl group, a lower alkoxycarbonylalkoxy group or a lower alkoxycarbonylalkylthio group, and R⁵ represents: ##STR17## wherein R⁷ represents a hydrogen atom, a halogen atom, a lower alkyl group or a lower alkoxycarbonyl group, and R⁸ represents a hydrogen atom, a halogen atom or a lower alkyl group.

3.75 g (27.1 mmol) of potassium carbonate was suspended in 50 ml of N,N-dimethylformamide (DMF). Then, 11.9 g (54.2 mmol) of 5-acetylamino-2-chloro-4-fluoro-thiophenol was dissolved in 80 ml of DMF, and then it was added thereto. Under stirring, 8.29 g (54.2 mmol) of methyl bromoacetate was dissolved in 20 ml of DMF, and it was added dropwise thereto at room temperature. After the reaction for 10 minutes, DMF was removed under reduced pressure, and then water was added to the residue, followed by an extraction with ethyl acetate. It was washed first with water and then with saturated brine and then dried with anhydrous magnesium sulfate. Then, the solvent was distilled off under reduced pressure, thereby to obtain crystals. Recrystallization was conducted with ethyl acetate/n-hexane, thereby to obtain 12.49 g of 5-acetyl-2-chloro-4-fluoromethoxycarbonylmethylthiophenol. The melting point was 125.0°-126.5° C.

1.0 g (3.1 mmol) of N- 4-chloro-2-fluoro-5-(1-methoxycarbonylethylthio)phenyl!-acetoimidoylchloride and 0.83 g (3.7 mmol) of a potassium salt of 3,4,5,6-tetrahydrophthalamic acid monomethyl ester were mixed in 20 ml of N,N-dimethylformamide, followed by heating and stirring at 70° C. for 2 hr. After it was allowed to stand to cool down, the solvent was distilled off under reduced pressure, then water was added to the residue, and then it was extracted with ethyl acetate. The organic layer was washed with water, followed by drying with anhydrous magnesium sulfate. The solvent was concentrated, thereby to obtain an oil-like substance. The residue was purified by silica gel column chromatography, thereby to obtain 0.66 g of N-acetyl-N- 4-chloro-2-fluoro-5-(1-methoxycarbonylethylthio)phenyl!-3,4,5,6-tetrahydrophthalamic acid methyl ester in the form of oil-like substance.

REFERENTIAL EXAMPLE 2 Production of N- 4-chloro-2-fluoro-5-(1-methylpropargyloxy)phenyl!nicotinamide (A compound that is represented by No. 46 in the aftermentioned Table 7 and by the general formula X!)

2.5 g (11.8 mmol) of 4-chloro-2-fluoro-5-(1-methylpropargyloxy)aniline and 2.53 g (25 mmol) of triethylamine were dissolved in 50 ml of 1,2-dichloroethane. 2.14 g (12 mmol) of chloronicotinoyl hydrochloride was added by small portions to this solution, while the reaction temperature was maintained at a temperature not higher than 35° C. Under room temperature, stirring was conducted for 2 hr. After the reaction, water was added to the reaction liquid, followed by extraction with ethyl acetate. Then, the organic layer was washed with water and then dried with anhydrous magnesium sulfate and then concentrated under reduced pressure. The obtained residue was recrystallized with a solvent mixture of n-hexane and ethyl acetate, thereby to obtain 2.5 g of pale yellow crystals, N- 4-chloro-2-fluoro-5-(1-methylpropargyloxy)phenyl!nicotinamide. The melting point was 157°-158° C.

Table 7 shows anilide derivatives X! which were obtained in manners analogous to that of the foregoing Referential Example 2, and Table 8 shows ¹ H-NMR absorption spectrum values thereof.

Example 4 Production of N- 4-chloro-2-fluoro-5-(1-methylpropargyloxy)phenyl!nicotinoylimidoylchloride (A compound that is represented by No. 51 in the aftermentioned Table 9 and by the general formula IV!)

5.00 g (15.7 mmol) of N- 4-chloro-2-fluoro-5-(1-methylpropargyloxy)phenyl!nicotinamide was added to 30 ml of benzene, and then 3.27 g (15.7 mmol) of phosphorus pentachloride was added thereto under stirring. This mixture was heated and stirred at 60° C. for 2 hr. After standing to cool down, the solvent and the like were distilled off under reduced pressure. 20 ml of methylene chloride was added to the residue. Under cooling with ice, 1.60 g (15.8 mmol) of triethylamine was added dropwise thereto. After that, 10 ml of n-hexane was added thereto. After removal of the resulting precipitate by vacuum filtration, the filtrate was concentrated under reduced pressure. The residue was purified by silica gel column chromatography, thereby to obtain 2.87 g of N- 4-chloro-2-fluoro-5-(1-methylpropargyloxy)phenyl!nicotinoylimidoylchloride in the form of yellow crystals.

Example 5 Production of N- 4-chloro-2-fluoro-5-(1-methylpropargyloxy)phenyl!-N-nicotinyl-3,4,5,6-tetrahydrophthalamic acid methyl ester (A compound represented by No. 57 in the aftermentioned Table 11 and by the general formula II!

2.75 g (8.2 mmol) of N- 4-chloro-2-fluoro-5-(1-methylpropargyloxy)phenyl!nicotinoylimidoylchloride and 1.81 g (8.2 mmol) of a potassium salt of 3,4,5,6-tetrahydrophthalamic acid monomethyl ester were mixed in 20 ml of N,N-dimethylformamide, followed by heating and stirring at 70° C. for 2 hr. After standing to cool down, the solvent was distilled off under reduced pressure, then water was added to the residue, and then it was extracted with ethyl acetate. The organic layer was washed with water and then dried with anhydrous magnesium sulfate and then concentrated. The residue was recrystallized from methanol, thereby to obtain 2.35 g of N- 4-chloro-2-fluoro-5-(1-methylpropargyloxy)phenyl!-N-nicotinyl-3,4,5,6-tetrahydrophthalamic acid methyl ester in the form of pale yellow crystals. The melting point was 115°-118° C.

REFERENTIAL EXAMPLE 3 Synthesis of N- 4-chloro-2-fluoro-5-(1-methylpropargyloxy)phenyl!-2-thiophenecarboxyamide (A compound that is represented by No. 77 in the aftermentioned Table 13 and by the general formula X!)

47.0 g (0.22 mol) of 4-chloro-2-fluoro-5-(1-methylpropargyloxy)aniline was dissolved in 200 ml of methylene chloride, and then 36.5 ml (0.26 mol) of trimethylamine was added thereto under room temperature. Under stirring, 38.7 g (0.26 mol) of tenoyl chloride was dissolved in 100 ml of methylene chloride, and then it was added dropwise thereto at a temperature from 5° to 10° C. After the dropwise addition, it was dried with anhydrous magnesium sulfate. The solvent was removed under reduced pressure, thereby to obtain crystals. Recrystallization from ethyl acetate/n-hexane was conducted, thereby to obtain 68.09 g of N- 4-chloro-2-fluoro-5-(1-methylpropargyloxy)phenyl!-2-thiophenecarboxyamide. The melting point was 143°-144° C.

In a stream of nitrogen, a potassium salt of 3,4,5,6-tetrahydrophthalamic acid monomethyl ester was suspended in 500 ml of N,N-dimethylformamide, and then under stirring 47.91 g (0.14 mol) of N- 4-chloro-2-fluoro-5-(1-methylpropargyloxy)phenyl!-2-thiophenecarboxyimidoylchloride was added thereto. It was heated to 70° C. and then stirred for 3 hr. After the reaction, the solvent was removed under reduced pressure, and then water was added to the residue. It was extracted with ethyl acetate and then washed with water and then dried with anhydrous magnesium sulfate. After removal of the drying agent, n-hexane was added thereto. Then, the precipitated crystals were removed by filtration. The filtrate was concentrated under reduced pressure, thereby to obtain crystals. Recrystallization from methanol was conducted, thereby to obtain 37.41 g of N- 4-chloro-2-fluoro-5-(1-methylpropargyloxy)phenyl!-N-(2-thiophenecarboxy)-3,4,5,6-tetrahydrophthalamic acid methyl ester. The melting point was 93°-96° C.

A herbicide of the present invention containing as the effective component an N-phenyltetrahydrophthalamic acid derivative I! or II! that is a compound of the present invention has a superior herbicidal activity against various weeds causing problems upon the submerged soil treatment in paddy fields, such as gramineous weeds such as nobie (barnyardgrass, Echinochloa spp.), broad-leaved weeds such as azena (flase pimpernel, Lindernia pyxidaria), kikashigusa (toothcup, Rotala indica), mizohakobe (waterwort, Elatine triandra), cyperaceous weeds such as tamagayatsuri (small-flowered umbrellaplant, Cyperus difformis) and hotarui (bulrush, Scirpus juncoides), and weeds such as konagi (Monochoria vaginalis). Furthermore, the herbicide has a superior herbicidal activity against various weeds causing problems upon the foliage treatment and the soil treatment in uplands, such as broad-leaved weeds such as karashina (indian mustard, Brassica juncea), aobiyu (slender amaranth, Amaranthus viridis), hakobe (chickweed, Stellaria media), shiroza (common lambsquarters, Chenopodium album), onamomi (heartleaf cocklebur, Xanthium strumarium), marubaasagao (tall morningglory, Ipomoea purpurea), yaemugura (catchweed bedstraw, Galium aparine), suberihiyu (common purslane, Portulaca oleracea), ichibi (velvetleaf, Abutilon theophrasti), amerika-tsunokusanemu (hemp sesbania, Sesbania exaltata), ebisugusa (sicklepod, Cassia obtusifolia), inuhouzuki (black nightshade, Solanum nigrum), spedwells, smart weeds, violets, tade (Persicaria longiseta) and its relatives, and sumire (Viola mandshurica) and its relatives, gramineous weeds such as inubie (barnyardgrass, Echinochloa crus-galli), enokorogusa (green foxtail, Setaria viridis), karasumugi (wild oat, Avena fatua), mehishiba (henry crabgrass, Digitaria ciliaris), seibanmorokoshi (johnsongrass, Sorghum halepense) and enbaku (oat, Avena sativa), cyperaceous weeds such as kogomegayatsuri (rice flatsedge, Cyperus iria) and hamasuge (nut grass, Cyperus rotundus), and commelinaceous weeds such as tsuyukusa (dayflower, Commelina communis). The herbicide of the present invention hardly injures major crops such as rice, wheat, corn and soybean.

Therefore, the herbicide of the present invention can be applied to upland, paddy field, orchard, pasture, turf, forest and non-crop land.

It is possible to process the herbicide of the present invention containing as the effective component an N-phenyltetrahydrophthalamic acid derivative I! or II! that is a compound of the present invention into an arbitrary form such as wettable powder, emulsion, granules, powder or flowable by using a pesticide adjuvant which is generally used in this field, such as an inactive solid carrier or liquid carrier and an emulsifying and dispersing agent. As these inactive carriers, there can be cited, for example, talc, clay, bentonite, kaolin, diatomaceous earth, calcium carbonate, wood flour, starch, gum arabic, water, alcohol, kerosene, benzene, xylene, n-hexane, acetone, N,N-dimethylformamide, glycol ether, and N-methylpyrrolidone.

Besides, it is possible to adequately incorporate auxiliary agents for formulation, such as spreader, diluent, surfactant and solvent.

Upon using as a herbicide N-phenyltetrahydrophthalamic acid derivative I! or II! which is a compound of the present invention, a suitable application dosage is variable according to related factors such as manner of application, object of application, time of application and occurrence condition of weeds, but in general the application dosage, as expressed as the amount of the effective component, is preferably from 0.5 g to 300 g per 1 hectare. An application dosage less than 0.5 g is not preferable, because a sufficient herbicidal effect can not be obtained. Even if an application dosage greater than 300 g is used, the herbicidal effect does not change so much. It causes only an economical disadvantage and may generate injuries. Therefore, it is not preferable. 1-300 g per 1 hectare is particularly preferable.

Furthermore, to use the herbicide containing an N-phenyltetrahydrophthalamic acid derivative I! or II! which is a compound of the present invention, it may be mixed with other herbicides, plant growth regulators, fungicides, insecticides, other pesticides, fertilizers and soil conditioners.

The following are Examples of herbicides according to the present invention, though compounds, carriers, adjuvants and the proportions of the ingredients are not limited to those in these examples. In these examples the amount of each component is indicated by parts by weight.

The following experiments are illustrative of the herbicidal effects of N-phenyltetrahydrophthalamic derivatives I! which are compounds of the present invention.

EXPERIMENT 1

(Flooded Soil Treatment)

Paddy soil (clay loam) was put into a pot so as to have a surface area of 1/15500 ares. Uniformly mixed seeds of several kinds of weeds, viz., nobie (barnyardgrass, Echinochloa spp.), broad-leaved weeds, hotarui (bulrush, Scirpus juncoides) and tamagayatsuri (small-flowered umbrellaplant, Cyperus difformis), were sown in the surface layer of the soil in each pot, and then paddy rice seedlings at the two- or three-leaved stage were transplanted into each pot to a depth of 2 cm, and water was fed into each pot so as to provide a 3 cm deep water layer on the soil surface. After 3 days, in other words at the initial stage of germination of nobie (barnyardgrass, Echinochloa spp.), a predetermined amount of a selected compound obtained in a manner analogous to Example 8 in the form of diluted aqueous solution was dropped into the water layer in each pot. After that, the pots were kept in a glass chamber to allow the paddy rice and the weeds to grow, and after the lapse of 4 weeks from the treatment with the selected compounds, the herbicidal effects and the degree of injury to the paddy rice were evaluated. The results are shown in Table 20. In the table, the herbicidal effects and the degree of injury to the paddy rice are indicated by numerical values, which have the following meaning.

5: completely killed

4: seriously injured

3: considerably injured

2: somewhat injured

1: slightly injured

0: not injured (normally grown)

EXPERIMENT 2

(Foliage Treatment)

Upon seedling stage (two- or three-leaved stage) of rice, cockspur (Panicum crus-galli), garden radish, aobiyu (slender amaranth, Amaranthus viridis) and mehishiba (henry crabgrass, Digitaria cliaris) which were grown on a cultivated soil put in pots of 1/15500 ares, a selected compound obtained in a manner analogous to Example 8, in suspended wettable powder, was sprayed to each plant. After that, the pots were kept in a glass chamber to allow each plant to grow, and after the lapse of 4 weeks from the treatment with the selected compounds the herbicidal effects were evaluated. The results are shown in Table 21. The evaluation of the herbicidal effects was similarly conducted as to that of Experiment 1.

EXPERIMENT 3

(Foliage Treatment)

Upon seedling stage (two- or three-leaved stage) of ichibi (velvetleaf, Abutilon theophrasti), onamomi (heartleaf cocklebur, Xanthium strumarium) (4L stage), noasagao (blue morningglory, Ipomoea indica) and ooinutade (pale smartweed, Persicaria lapathifolia) which were grown on a cultivated soil put in pots of 1/8850 ares, a selected compound obtained in a manner analogous to Example 8, in suspended wettable powder, was sprayed to each plant. After that, the pots were kept in a glass chamber to allow each plant to grow, and after the lapse of 4 weeks from the treatment with the selected compounds the herbicidal effects were evaluated. The results are shown in Table 22. The evaluation of the herbicidal effects was similarly conducted as to that of Experiment 1.

The following experiments are illustrative of the herbicidal effects of N-phenyltetrahydrophthalamic derivatives II! which are compounds of the present invention.

EXPERIMENT 4

(Flooded Soil Treatment)

Paddy soil (clay loam) was put into a pot so as to have a surface area of 1/15500 ares. Uniformly mixed seeds of several kinds of weeds, viz., nobie (barnyardgrass, Echinochloa spp.), broad-leaved weeds, hotarui (bulrush, Scirpus juncoides) and tamagayatsuri (small-flowered umbrellaplant, Cyperus difformis), were sown in the surface layer of the soil in each pot, and then paddy rice seedlings at the two- or three-leaved stage were transplanted into each pot to a depth of 2 cm, and water was fed into each pot so as to provide a 3 cm deep water layer on the soil surface. After 3 days, in other words at the initial stage of germination of nobie (barnyardgrass, Echinochloa spp.), a predetermined amount of a selected compound obtained in a manner analogous to Example 11 in the form of diluted aqueous solution was dropped into the water layer in each pot. After that, the pots were kept in a glass chamber to allow the paddy rice and the weeds to grow, and after the lapse of 4 weeks from the treatment with the selected compounds, the herbicidal effects and the degree of injury to the paddy rice were evaluated. The results are shown in Table 23. The evaluation of the herbicidal effects was similarly conducted as to that of Experiment 1.

EXPERIMENT 5

(Foliage Treatment)

Upon seedling stage (two- or three-leaved stage) of rice, cockspur (Panicum crus-galli), garden radish, aobiyu (slender amaranth, Amaranthus viridis) and mehishiba (henry crabgrass, Digitaria cliaris) which were grown on a cultivated soil put in pots of 1/15500 ares, a selected compound obtained in a manner analogous to Example 11, in suspended wettable powder, was sprayed to each plant. After that, the pots were kept in a glass chamber to allow each plant to grow, and after the lapse of 4 weeks from the treatment with the selected compounds the herbicidal effects were evaluated. The results are shown in Table 24. The evaluation of the herbicidal effects was similarly conducted as that of Experiment 1.

EXPERIMENT 6

(Foliage Treatment)

Upon seedling stage (two- or three-leaved stage) of ichibi (velvetleaf, Abutilon theophrasti), onamomi (heartleaf cocklebur, Xanthium strumarium) (4L stage), noasagao (blue morningglory, Ipomoea indica) and ooinutade (pale smartweed, Persicaria lapathifolia) which were grown on a cultivated soil put in pots of 1/8850 ares, a selected compound obtained in a manner analogous to Example 11, in suspended wettable powder, was sprayed to each plant. After that, the pots were kept in a glass chamber to allow each plant to grow, and after the lapse of 4 weeks from the treatment with the selected compounds the herbicidal effects were evaluated. The results are shown in Table 25. The evaluation of the herbicidal effects was similarly conducted as that of Experiment 1.

EXPERIMENT 7

(Flooded Soil Treatment)

Paddy soil (clay loam) was put into a pot so as to have a surface area of 1/15500 ares. Uniformly mixed seeds of several kinds of weeds, viz., nobie (barnyardgrass, Echinochloa spp.), broad-leaved weeds, hotarui (bulrush, Scirpus juncoides) and tamagayatsuri (small-flowered umbrellaplant, Cyperus difformis), were sown in the surface layer of the soil in each pot, and then paddy rice seedlings at the two- or three-leaved stage were transplanted into each pot to a depth of 2 cm, and water was fed into each pot so as to provide a 3 cm deep water layer on the soil surface. After 3 days, in other words at the initial stage of germination of nobie (barnyardgrass, Echinochloa spp.), a predetermined amount of a selected compound obtained in a manner analogous to Example 14 in the form of diluted aqueous solution was dropped into the water layer in each pot. After that, the pots were kept in a glass chamber to allow the paddy rice and the weeds to grow, and after the lapse of 4 weeks from the treatment with the selected compounds, the herbicidal effects and the degree of injury to the paddy rice were evaluated. The results are shown in Table 26. The evaluation of the herbicidal effects was similarly conducted as that of Experiment 1.

EXPERIMENT 8

(Foliage Treatment)

Upon seedling stage (two- or three-leaved stage) of rice, cockspur (Panicum crus-galli), garden radish, aobiyu (slender amaranth, Amaranthus viridis) and mehishiba (henry crabgrass, Digitaria cliaris) which were grown on a cultivated soil put in pots of 1/15500 ares, a selected compound obtained in a manner analogous to Example 14, in suspended wettable powder, was sprayed to each plant. After that, the pots were kept in a glass chamber to allow each plant to grow, and after the lapse of 4 weeks from the treatment with the selected compounds the herbicidal effects were evaluated. The results are shown in Table 27. The evaluation of the herbicidal effects was similarly conducted as to that of Experiment 1.

EXPERIMENT 9

(Foliage Treatment)

Upon seedling stage (two- or three-leaved stage) of ichibi (velvetleaf, Abutilon theophrasti), onamomi (heartleaf cocklebur, Xanthium strumarium) (4L stage), noasagao (blue morningglory, Ipomoea indica) and ooinutade (pale smartweed, Persicaria lapathifolia) which were grown on a cultivated soil put in pots of 1/8850 ares, a selected compound obtained in a manner analogous to Example 14, in suspended wettable powder, was sprayed to each plant. After that, the pots were kept in a glass chamber to allow each plant to grow, and after the lapse of 4 weeks from the treatment with the selected compounds the herbicidal effects were evaluated. The results are shown in Table 28. The evaluation of the herbicidal effects was similarly conducted as that of Experiment 1.
